Answer:
Median: 4.5
Mode: 4
Mean: 6.7
Step-by-step explanation:
First lets find the median, the number in the middle. To do this we need to put this data set in ascending order
1,4,4,4,4,5,7,8,15,15
The two numbers in the middle are 4 and 5. Now we must add these two numbers together and then divide by 2.
Nexte lets find the mode, the number that occurs the most. 4 appears 4 times, which is the greatest amount.
Now lets find the mean. First we need to find the sum of these 10 numbers
Next we have to divide by the number of data points, which is 10
We are asked to solve for the value of "x" such that when it is added in the original area of the park it will double the area. Let us compute first the area of the original dog park (A1) and the solution is shown below:
Area = Lenght*Width = L*W where L=30 yards and W=20 yards
Area = 30*20
Area = 600 yards squared
Solving for the x, when x is added to both sides which double the area:
A1*2 = (L + 2x)*W
600*2 = (30+2x)*20
1200 / 20 = 30+2x
60 = 30 + 2x
60-30 = 2x
30/2 =x
15 = x
The value of x is 15 yards.
Answer:
5:6
Step-by-step explanation:
the ratio before would be 10/12 so you would have to divide both sides by 2 so you would get 5/6.Hope this helped
Hey There!
The answer to your problem is 
or 
both answers are correct!
<u>Step 1: Subtract x²+12 from both sides.</u>
−7x−(x²+12)=x²+12−(x²+12)
−x²−7x−12=0
<u>Step 2: Factor left side of equation.</u>
<u>Step 3: Set factors equal to 0.</u>

Answer:
Area = L²-5L
Step-by-step explanation:
Area = length * width
Length = L
Width = L - 5
Area = L * (L-5) = L²-5L
